The operative technique for combined fusion of the knee and rotationplasty of the limb in the management of congenital deficiency of the femur is presented. The technique described allows earlier definitive prosthetic fitting of a child with proximal femoral deficiency; it has reduced the number of operative procedures needed to obtain the optimal function from that deficient limb; and it has enabled these procedures to be performed at an earlier age. The technique differs from those previously described and represents a significant improvement in management of the patient with femoral deficiency

We report the case of a child with cerebral palsy and spastic diplegia treated for bilateral fixed flexion of the knee by bilateral hamstring lengthening. An attempt to straighten the legs from 90 degrees to 20 degrees flexion damaged the sciatic nerve. There are no objective means of estimating how much deformity can be reduced safely. We present a method of calculating the extra strain in the sciatic nerve produced by reducing a flexion deformity. The result, combined with clinical judgement, provides guidelines for safe corrective surgery

Subluxation of the hip presenting for the first time in a child over the age of four years is rare. We report ten cases treated over nearly 11 years by the senior author (JAF). We describe the surgical procedures and the results, at maturity, of nine of the ten patients. At a mean follow-up of nearly nine years, the clinical outcome was good in all ten children by the criteria of Ponseti. Radiological assessment showed that three hips remained subluxed, and that four had avascular necrosis of the physis. We advise a one-stage procedure, correcting both the femur and acetabulum

1 . This case of post-traumatic osteochondritis of the lower tibial epiphysis is important because the condition is rare. 2. The similarity to osteochondritis in other sites dating from a single injury is noted. 3. The ankle joint bears more body weight per surface area of articular cartilage than other weight-bearing joint surfaces. It is of interest that regeneration took place in spite of the fact that the child continued to bear weight and that the joint was immobilised for only two months, beginning four months after the original injury

Both knees of 50 normal children aged from birth to 18 years were examined by ultrasonography to measure the angles of the bony intercondylar and the cartilaginous sulcus on the patellar surface of the femur. The osseous angle was inversely related to the age of the child and was completely flat in the youngest children. During growth it gradually gained depth to assume the shape of the overlying articular cartilage by adolescence. At all ages, however, the angle of the cartilaginous sulcus was between 134 degrees and 155 degrees. This suggests that the configuration of the patellar articulation is already well developed at birth

Redisplacement of unstable forearm fractures in plaster is common and may be the result of a number of factors. Little attention has been paid to the influence of immobilisation with the elbow extended versus flexed. We prospectively treated 111 consecutive children from two centres with closed forearm fractures by closed reduction and casting with the elbow either extended (60) in China or flexed (51) in Israel. We compared the outcome of the two groups. There was no statistically significant difference in the distribution of the age of the patients, the site of fracture or the amount of angulation and displacement between the groups. During the first two weeks after reduction, redisplacement occurred in no child immobilised with the elbow extended and nine of 51 children (17.6%) immobilised with the elbow flexed. Immobilisation of unstable forearm fractures with the elbow extended appears to be a safe and effective method of maintaining reduction

1. A rationale of subtrochanteric osteotomy with derotation and varus angulation in the treatment of Perthes' disease is suggested. 2. Three months after operation the child returns to a normal unrestricted life. 3. The anatomical results in twelve such operations with an average follow-up of two years and five months are presented. In five children the results were "very good," in four "good," in one "fair" and in one "bad.". 4. These results seem to compare favourably with those observed after conservative treatment of two, three or more years duration

A total of 33 children were treated for acute traumatic dislocation of the elbow between 1994 and 2002; 30 dislocations were posterior and three anterior. Eight children had a pure dislocation and 25 had an associated fracture of the elbow. Two had compound injuries. Two children had injury to the ulnar nerve, one to the radial nerve and one to the median nerve together with injury to the brachial artery. Twenty required open reduction. Complications included pseudarthrosis of the medial epicondyle in one child and loss of flexion and rotation of between 10° and 30° in ten others. Meticulous clinical and radiological assessment is mandatory in children with dislocation of the elbow to exclude associated injuries. The results were excellent to good in 22 patients, fair in ten and poor in one

Aims

To analyze outcomes reported in trials of childhood fractures.

Growth at the proximal tibial epiphyseal plate of the rat has been measured following three different growth-stimulating procedures. These were proximal periosteal release, distal periosteal release and full periosteal stripping of the diaphysis. A new radiographic method using a photographic technique has made it possible to take accurate measurements of the rate of long-bone growth in small experimental animals. From the results of this animal series we conclude that proximal tibial periosteal division is likely to be the most effective of the three procedures when used to correct leg-length discrepancy in the growing child

Surgical treatment of hydatid bone disease is rarely completely successful because radical excision is only possible at certain sites and secondary infection frequently occurs. Antihelmintic drugs have in the past been only palliative due to poor absorption and consequent low concentration in serum or cysts. We report five patients with Echinococcus granulosus infestation treated with a new chemotherapeutic agent albendazole; in two it was given postoperatively, in two pre-operatively and one child is being followed expectantly. We believe that a combination of chemotherapy and surgery may be efficacious in the treatment of hydatid bone disease

The behaviour pattern of the scoliosis associated with osteoid osteoma or osteoblastoma of the spine is described. In patients presenting with symptoms at or around skeletal maturity, the scoliosis is postural. Excision of the lesion ensures complete resolution of the curve. In the growing child, however, an initial postural scoliosis may develop vertebral rotation with structural characteristics. The magnitude of the curve and the associated vertebral rotation is dependent on the time interval between the onset of symptoms and the surgical treatment. Although removal of the lesion usually results in regression of the curve, a prolonged delay in treatment may result in a progressive structural scoliosis. A possible mechanism for the behaviour of the scoliosis is discussed

We have reviewed 61 children treated for septic arthritis from 1972 to 1981. The diagnosis in all cases was confirmed by bacteriology or by radiographic changes. Routine arthrotomy was not performed, but most patients had a joint aspiration. The management and outcome are described. We suggest that arthrotomy should be selective rather than mandatory. Septic arthritis of the hip in infants requires arthrotomy, but in the older child an infected hip can be treated by aspiration if the duration of symptoms is less than four days; arthrotomy may be needed if there has been more delay. Infected joints other than the hip can be satisfactorily managed by aspiration

Dorsiflexion has been studied in three normal feet and in three feet with talipes equinovarus to determine the anatomical features which might contribute to the failure of operative treatment to correct the deformity. In the normal feet the movement of dorsiflexion was found to be essentially rotatory in nature and not simply hinging; as dorsiflexion proceeds the fibula moves forwards relative to the os calcis and the calcaneal tendon. In the club feet a posterolateral tether was found; this prevented fibular movement and blocked dorsiflexion. As a result of this study a posterior and lateral release is advocated for the operative correction of the hindfoot in a child with a club foot deformity, particularly under the age of a year

A new radiological technique is presented in which serial axial radiographs of the patellofemoral joints are taken under conditions in which the muscles about the knee and hip are contracted in a manner similar to that during weight-bearing. A form of analysis has been developed whereby patellar rotation can be measured in two planes and femoral rotation about its long axis inferred. A population of asymptomatic adults and children was investigated in this way and their results (regarded as normal) compared with those in fifteen children with idiopathic chondromalacia patellae. In the normal child the femur rotates medially with the onset of muscle activity; by contrast the children with chondromalacia show a reversal of this mechanism

1. Trigger thumbs present at birth can be safely watched for twelve months because there is an expected spontaneous recovery rate of at least 30 per cent. 2. Trigger thumbs in children first noticed between the age of six to thirty months can be safely watched for six months because there is an expected spontaneous recovery rate of about 12 per cent. 3. Delayed operation left no residual contracture of the interphalangeal joint provided the release was done before the age of four years. 4. Operation is recommended if the child is over the age of three years when first seen

We carried out extensible endoprosthetic replacement of the proximal or total humerus in 18 children aged between six and 12 years, after resection of primary bone tumours mainly for osteosarcoma and Ewing’s sarcoma. In 11 patients we performed 44 lengthening procedures, with an average of two per child annually and a mean total extension of 29.9 mm per patient. We were able to achieve lengthening of the operated limb with few complications and a mean functional rating of 79.3% according to the Enneking system. Progressive lengthening of these prostheses does not adversely affect the overall function of the arm, and superior subluxation of the head of the prosthesis has not been a problem

Objectives

Aims

To examine the relationship of sex steroid hormones with osteopenia in a nationally representative sample of men in the USA.

We reviewed the cases of 38 children with 45 congenitally dislocated hips who presented for primary treatment after the age of three years. Of these, 34 hips were managed by the 'direct approach' of Somerville and Scott (1957); 14 of these required secondary operations for subluxation, often with a poor outcome. Eleven hips were treated by combined pelvic and femoral osteotomy which, in general, gave good results. At a mean follow-up of 16.7 years, 80% of the whole series had a good or excellent clinical result and 51% were good or excellent radiologically. Simultaneous correction both above and below the hip is considered to be the best treatment for the older child with congenital hip dislocation
